Question
Consider an IP subnet with prefix 123.45.67.0/25. Assume that one router is connected to the subnet. Which of the following statements are correct? There are 128 addresses on the subnet. 123.45.67.46 is a valid address on the subnet. Assume that another port on the router is connected to 123.45.67.128/25. The router can then aggregate the two subnets to one prefix: 123.45.67.0/24. 123.45.67.146 is a valid address on the subnet. A computer on the subnet sending an IP packet to address 123.45.67.67, will send it through the router. Up to 255 different computers can be connected on the subnet at the same time.Explanation / Answer
1- false there are 126 addresses on the subnet rather then 128 .
2-true 123.45.67.46 is a valid address because the starting address on host is 123.45.67.0 and it ends on 123.45.67.126
3- false it cannot be done
4-123.45.67.146 is an invalid address on the subnet because starting address on host is 123.45.67.0 and it ends on 123.45.67.126 so its in valid .
5-true - because its on the same subnet so can send through the router .
6- false only upto 254 computers can be conected on the subnet at the same time because it is an class A ip address and it can accomodate upto 254 computers.
